Opengl(Win)

环境： https://github.com/wlxklyh/LearnOpenglEmpty

工程地址： https://github.com/wlxklyh/StudyOpenGLVulkanDXMetal/tree/master/Opengl/Win

教程： https://learnopengl-cn.github.io/

Chapter1 getting_started

1.1.hello_window

1.2.hello_window_clear

2.1.hello_triangle

2.2.hello_triangle_indexed

2.3.hello_triangle_exercise1

2.4.hello_triangle_exercise2

2.5.hello_triangle_exercise3

3.1.shaders_uniform

3.2.shaders_interpolation

3.3.shaders_class

3.4.shaders_exercise1

3.5.shaders_exercise2

3.6.shaders_exercise3

左下角是(-0.5,-0.5,0) clamp to (0.0,0.0,0.0) 所以黑色

4.1.textures

4.2.textures_combined

4.3.textures_exercise1

4.4.textures_exercise2

4.5.textures_exercise3

4.6.textures_exercise4

5.1.transformations

6.1.coordinate_systems

//省略了

6.2.coordinate_systems_depth

//省略了

6.3.coordinate_systems_multiple

用了EBO绘制 左右面 上下面的 UV是相邻的 所以看起来是被拉伸了。

7.1.camera_circle

//see 7.4.camera_class

7.2.camera_keyboard_dt

//see 7.4.camera_class

7.3.camera_mouse_zoom

//see 7.4.camera_class

7.4.camera_class

Chapter2 lighting
